PowerPC :: Titanium Powerbook Logic Board Has A Broken Screen
May 8, 2008
I'm looking to get this titanium powerbook but it has a broken screen, possibly bad backlight? I can get it for a good price and I would love to have it to replace my ibook. I don't know the specs for sure but I am positive I think it's the DVI version since it has the keyboard that looks like the ibooks(same placement for the keyboard release latches).The guy said it worked fine on an external monitor but just recently he said it won't boot now and it now makes a high-pitched whining sound. Anyone know what that is? I'd like to use it as a headless mac until I locate a new screen for it.

I was using my trusty powerbook 500 mhz and when i closed the screen while the machine was on, after @ 1/2 hour i opened the screen up and NOTHING!. i restarted and nothing again, the caps lock key will light up, so i am assuming the power supply is ok. No chime and black screen, any suggestions on what it might be...im thinking logic board, if so what ones will fit that model

I had a fault where my powerbook would not start up. Apple replaced the logic board and now the screen is a very strange colour and flickers.In the video I use the hot corner and the dog changes to the right colour but the windows do not. its very strange.I will have to take it back to apple in the new year but is there anything I can do to improve the image. Its so hard to look at like this.

I brought my powermac into the apple store to confirm what I already thought - the logic board on my g5 is done.I'm putting it up on CL with full disclosure, but I was wondering what I should ask for it? Here are the specs, what would you pay?
powermac dual 1.8 g5
2gb ram (512x4)
80gb HDD
ATI Radeon 9800 XT 256mb
superdrive

I'm still working on this deal to buy a used 12" PB. The seller says that she just replaced the logic board, hard drive, and battery. Now, I see this as a negative. Obviously the computer was having problems, she spent a bunch of money fixing it, and is now selling it anyway. What do you think? Is it a negative that it had problems and needed to be fixed? Or is it a positive that it has a brand new logic board that will theoretically last longer than an original one?

I bought my first Mac (iBook) last December. However, it is now dead from logic board failure. I was looking at Macbooks but they are very expensive, which is why I bought the iBook in the first place. So now I'm looking at 15" PowerBook G4. My question is: If having a G4 proves too difficult in the next few years (PowerPC compatibility and speed), could I put a logic board from a 15" MBP in the PB?

I was attempting to replace the hard drive in my eMac, but for instructions I HAD to follow some darn take-apart guide that said pull out the connection for the power button cord from the logic board. I didn't know that it was SOLDERED in there, and now I can't complete putting my eMac back together without doing so.
Can this be fixed without having to send it to Apple? Does it HAVE to inolve soldering, or is there an alternative? Is there a way I can temporary have my eMac power on until I get the connector fixed?

I'm having my pb repaired from my casing warping. I brought it and the and they agreed to fix it. He ordered the parts and said when they arrive they would call me to bring it in. I guess they could do it at the store ( )i'm surprized it wasn't sent out. ne woot on the order sheet it says "Board, Logic, 1.5 GHz 64MB VAM". Now my question is I did a BTO and upgraded the VRAM to 128. Did he order the wrong part? Will it still work?

My girlfriend has a 12" G4 Powerbook that she claimed was getting really hot. I noticed it was as well, so I installed iStat Pro and saw that the fan was spinning at 0 RPM. So obviously something is wrong. I read a few posts on people having problems with the logic board, which would also cause the fan not to work. However, the computer runs fine, the fan just doesn't turn on when it gets hot. I haven't (and don't plan to) let it get so hot that it would shut itself off or burst in to flame or whatever happens. I understand it's out of Applecare, but I would prefer to fix it myself on the cheap. I'm perfectly capable and willing to replace the fan, but before I crack it open I would like to know if there is a simple way to see if my problem is simply a dead $30 fan, or a $500 logic board.

I recently took my 15in 1.5ghz powerbook to an AASP and was told that my logic board needed to be repleaced. He quoted me $369 and told me the turn around was going to be 4-5 days. I asked him just to be sure: This would include a logic board replacement and would only cost $369? He confirmed that it shouldn't cost more than that. Being the creature of habit I am I decided to take it to a Genius Bar for a 2nd opinion. My appt is tomorrow and I decided to research it further before I went. I have read other reports claiming that Apple charges upward of 500-800 to replace the logic board. Does anyone know if the replacement for the logic board is supposed to cost that much? I don't expect someone to know exactly but I was wondering if anyone has any reports or experience with this.

Hoping that some of you here still own or have owned Powerbooks recently... I have a PB G4 1.67ghz that I bought in July 2005. Since then, it's seen the back of the Apple Store several times to replace three logic boards, a screen, and a SuperDrive, with the most recent instance being the third logic board replacement. This has left the future of my laptop in uncertainty, as the warranty expires this July. In the past, I've owned several Macs for 5 years or more, including my beloved G4 Cube, so I'm no stranger to sticking with my Mac until it's absolutely necessary to upgrade... and financially, I was planning for this computer to last me another 2 years before I had to upgrade.

I have a powerbook g4 15" 1.5Ghz. My VRAM is shot and my computer keeps on going into panic mode or gets hot and just stalls and I have too reboot manually. I just purchased another logic board off of ebay, yes I'm a very brave guy, I installed the new/used logic board and I now see that the ribbon cable recepticles for the keyboard and finger pad are not on the new logic board. Obviously I bought the wrong board. Is it possible to still use it somehow like buy a new top plate or buy an external keybord? The top plate I have now has the fat ribbon cable and also the small one. Can I just get the proper cables? If so which ones are they?

I've searched high and low for any and all alternatives to working with my, shall we say, "experienced" Powerbook Titanium, despite it's age(it's not old, it's chronologically advanced!). After looking things up and being able to think of nothing, I figured I'd finally register here and hope for some good advice from people who possibly know more about Mac hardware than I do.I received my laptop in June of 2002(it was likely bought either that month or April) from my father. As far as I was aware, it was a brand new Powerbook bought from Comp USA...with the latest specs and peripherals at the time. After 7 years of using and loving my laptop(despite the fact the battery is completely dead, both hinges are broken and removed to keep the wires from accidentally being cut until I can afford new ones, and the CD drive no longer working), it's come to a point where I'm needing to try to breath even a little new-found life into my true love...or be stuck using "The Rex", my overbearing Desktop PC with its snooty Windows XP and massive noise-creating fans.

I came across a powerbook g4 (dvi, 15 inches, 800mhz, 512mbs, airport card, dvd-rom + cd-rw, after market battery never used and after market ac adapter)) sold "as is" on craig's list. I picked it up for $50. It had everything but the hdd. The first time i plugged it (without hdd) I got the flashing ?. I swapped in another hdd and all I would would get the apple chime followed three soft beeps (nothing on the screen). And then eventually, I would power it on and the only sign of life I would get is the caps lock light on, and the num lock light only if I hit F5 (again nothing on the screen). If i let the powerbook sit without the battery for a while, then I would get the apple chime again but then the power cut out right away. This happens with the adaptor or the battery only which leads me to believe it's not the dc-in board. I have tried different ram, disconnected the airport card, disconnected the cd player. I have tried resetting the PMU and every key combination to reset the PRAM (it never seemed to make a difference).

Love my 12" PB 1.5ghz. Running Leopard on it. But the memory cap of 1.25gb with 256gb soldered on to the board (and only one memory slot) bugs me. Especially since this is the same logic board that goes into the 12" iBooks last revision that have 512mb soldered on to their boards. (Their memory cap is 1.5gbs and it does make a difference, especially on the 1.42ghz iBooks).I just asked Gary Dailey of Daystar if they could solder a 1 gig chip on the board.. seems like a better "upgrade" than overclocking with Leopard's memory demands Will let MR know if this can be done. If so, i'm in.

I have a 17" PB, 1.33 ghz with 1.76gb ram. In September it gave signs of the hard drive failing. It would crash right after booting and then not boot at all.If I booted into target disk mode i could still access the files. I backed everything up and did many versions of trying to reformat / reinstall my OS to no avail. When Leopard came out I went through the process again to see if that might help but it didn't. Today I replaced the HD and now it still won't boot at all. It goes to the grey apple screen with the rotating loading icon and stalls. I've let it sit there for 10 minutes or more.

I have a PowerBook G4 15" 1.33GHz that up until now ran flawlessly. Today I was watching a movie on it with some friends when it randomly shutdown. Since then, it no longer turns on. The battery is fully charged and there is no problem with my AC adapter. With just the battery, nothing happens when I press the power button. When the AC adapter is plugged in and I press the power button, the optical drive spins at full speed for a few minutes and then the PowerBook shuts itself down again. I have attempted reseting pram and pmu with no success. I think it could be a dead logic board but I'm not sure. Would it be worth the money to buy a new logic board or should I just part it out?

First Mac Attack, must say I like working on these things, I'm working on a friends late 2004 ibook g4 that seems to boot up fine, but with lines across screen exactly like this one found in google images. Most of the info I've come across seems to point to a logic board failure, but also have seen posts relating to LCD failure. wondering if any here have encountered this and what eventually found was problem. This ibook is litterally on the verge of just being replaced anyway. I'm only working on it because It's a first, and believe the education is valuable.

I purchased a 1.33 G4 14 inch ibook exactly 13 months and eight days ago. The logic board is toast as of today. i.e. flashing colors and flickering screen. I took it back to where I purchased it and many other apple items {powermacpac it Portland Oregon}...and I was told that it was a $600 dollar repair...unbeleivable...I now have a $1050 dollar paperweight. I called apple support to find out if they would fix the computer since we were so close to the warranty end date. n the end...I shoulda bought applecare.

Some of you probably will remember my post a week ago, saying that my MBP DVD drive killed my OSX Installation DVD. here is the conclusion of it, I took it authorised service center here in North Thailand. Waited for a week they sad they will change DVD drive and today it finally arrived. Around 11am they called me and said dude, we changed the drive the problem is still there cant install system. Your "Logic Board' is screwed, you have to wait at least 1 week for a new one.
Now what is logic board? Is that main board? Is it possible for computer to still work with a broken mainboard? I mean I didnt damage it, I had kernell panic and tried to re-install OSX so how could that killed my MPB? I still could boot into disk utility and format the drive was just unable to copy files.To be honest my MBP is 3 months old, i took a good care of it. And I'm very very very dissapointed in apple computers now, expensive and damn un-reliable.

i have a friend who has a powerbook g4 (black keyboard) that was sold to him for very cheap, unfortunately the screen was torn off the base of the computer. Its in perfect running condition but he cant take it anywhere because the screen needs to be supported against a wall as it cant stand on its own. Is there any inexpensive way to fix the screen and restick back to the base of the laptop and if the only way to go is get a professional to do it, how much would it cost him to get it fix. He got the computer for 50 bucks so having the computer work perfectly even if he has to spend at most 300 dollars would be great.

I was given a free G3 Pismo Powerbook. DOA and traced to dead internal battery. Successfully replaced and the unit is now alive except I have determined the video chip is toast. Everything works except display to all output types is shot - bad colour, vertical lines, huge cursor etc.
Lots of logic boards available on ebay for about $30. This would make a decent starter computer for my young boys.
I'm looking for good instructions to replace the board.
SPECS
Pismo Bronze Keyboard
G3, 400 Mhz
512 MB ram
10 GB drive
DVD ROM optical drive
2 USB + 2 firewire 400 + S video + RGB
